To all whom it may concer/n.'

ABe yit known `that I, BERNARD H. HARTLEY, a citizenof the UnitedStates, residing at VRed House, yin zthe county of Putnam and State of WestJ Virginia, have invented new and useful Improvements in Knives, of which the following vis a specification.

|lfhis invention relates yto Ypocket knives and .has for one of its chief characteristics, the provisionof a knife *wherein thehandle is designed to completely enclose the'blades when'the'latter are in folded'position, to the exclusion of dampness'and'foreign matter which frequently has a detrimental effect nponftherbladesvoftheknife.

Another'. important object'of the invention resides in providingthe knife with `a two part handle, tthe :respective parts being .hingedly connected together, the blades pivoted to fold in superimposed relation within one of the parts, and when-extended for use clamped betweenthe respective parts ofthe handle to prevent accidental closing of the blades when the `knife .is in use.

Another object of the invention resides in the provision of a novel construction of fastening means for holding the respective parts of the handle fixed relatively in normal position whereby the said parts can be readily and easily locked together or released to permit access to the blades as the occasion requires.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

1n the drawings forming part of this application like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a perspective view of the knife in its normal position.

Figure 2 is a longitudinal sectional view therethrough.

Figure 3 is a plan view of the knife showing the handle opened and the blades in folded position.

Figure 4 is a similar view showing the blades extended for use.

Figure 5 is a view showing the blades in extended position and the sections of the Vboth ends .thereof as at 12. AThe sectionor part 11 constitutes a coveror closure forfthe hollow portion 11l towhich it is hingedly secured as at 13. The .blades of the knife are indicated at 14 and have their corresponding extremities pivoted between the sides of the member 10 of thehandle so that the blades can be swung toward each other in overlapped relation and folded within the member 10 of the handle,or projectedA through `the opened ends of themember 10 and extended to a position for use. When the blades are in an extended position, they lie f below the upper surface of the member 10, this providing a space or ,pocket for the reception of .the enlargement 15,. formed.. at vthe ends of the under side of the member 11 of the handle. Consequently, when this member 11 is folded upon the member 10, with the blade in an extended position, the enlargements 15 repose upon the blade and serve to effectively retain the latter in an extended position and against any relative movement with respect to each other' or regard to the handle in its entirety. The knife can thus be used in the usual manner without any possibility of the blades accidentally closing. Vhen the blades are folded in superimposed relation within the member 1() of the handle the member 11 arranged in its normal position, the blades are completely housed and enclosed between the respective members of the handle, to the exclusion of the dirt and dampness, which usually has a bad effect upon the blades.

In order to secure the respective members of the handle together, l preferably make use of a slide such as indicated in Figure 7, the slide comprising two parallel members 2O and 21 respectively `these members being arranged at the opposite sides of the back wall of the member 10 of the handle. These members are connected together by the stem 22 and one of these members which may be,

termed a manipulating member is provided with a head 23. The rear wall of the member *of the handle upon which the slide yis mounted, is provided with an elongated notch or yrecess 2li in which the manipulating member of the slide operates. One ofthe parallel members 2O of the slide is formed with inwardly directed flanges 25 arranged 'in spaced relation, while one edge of the member 11 of the handle isl provided with notches27, there being one of these notches 4Jfor each of the flanges referred to which'receive-s the Aflanges when the slide isy in one" position. The notches 27v also communicate with the slots 28 formedl in the edge of the member 11 so that subsequent to positioning the anges within the notches, and moving the slide longitudinally ofthe handle, the

' flanges are positioned within the notches .2S

and thereby hold the respective members of the handle fixed relatively. The construe4 vtion. is very simple andl consequently the slide can be' readily andeasily manipulated p to either lock the members of the handle fixed relative or release the' same to permit access being had to the blades la. The component parts of the knife can be constructed of any suitable material, while the knife itself may vary in `size and configuration without departing from the spirit of the in vention.

While it is believed that from the forey going description the nature and advantages of the invention will be readily apparent,-I

f described and that such changes 'may be redesire to have itunderstood that l do not limit myself to what is herein shown and sorted to when desired as fall within the scope of what is claimed.

llVhat l claim is: I

lll pocket knife of the character described comprising a sectional handle hingedly connected together, one ofsaid sections being hollow and open at both ends,1blades pivoted within the hollow section and being adapted to be folded therein in superimposed rela-- tion,said` bladesl lying below the upper sur face of the hollow section and providing a space on the outer side of their pivotal con` neetion with the hollow section, 'an enlargement formed at each end of the o-pposite section of eachhandle and. being adapted to be received in the respective spaces, a slide for connecting thel sections together when folded andI including spaced parallel members arranged on opposite'sides of the free side of the hollow section, a'stem connecting municating with slotsso that the flanges.

may be positioned within the slots'to hold the respective members f' of the handle relatively fixed. 4

In testimony whereof I aiX my signature.
